qRegisterMetaTypeStreamOperators(“PhotoFormat”);</p>
<p>And declare it with next prototypes:
QDataStream &operator<<(QDataStream &out, const PhotoFormat &obj);
QDataStream &operator>>(QDataStream &in, PhotoFormat &obj);</p>
<p>It need for serialization class and usefull to use custom types with QSettings, for ex, implemenations of ‘operator<<’:
QDataStream & operator <<(QDataStream &out, const PhotoFormat &obj)
{
QString name = obj.getFormatName();
QSizeF size = obj.getSize();
qreal dst1 = obj.getTopPateDistance();
qreal dst2 = obj.getNoseChinDistance();
}</p>
<pre><code>out << name << size << dst1 << dst2;
return out;</code></pre>
<p>Code from real project :-)</p>
